I was able to steal a few minutes to work on this – is the following chart clear to you?
In the future, I will need to sink more time into visuals! I took the relevant parts of my table and the other dude’s (TM) graph and made some more-angular-than-squiggly lines to connect them to each other. Look at that, then read my prior post, and see if it makes sense to you now. If it’s still unclear, I will try something else.
